"Eon:" "Coward!" "You can't hide from me!" "Adult Ben:" "I'm not hiding." "I'm making an entrance." "Eon:" "Tennyson!" "Agh!" "Adult Ben:" "Really, eon?" "Attacking me all by yourself in my own headquarters." "You call that a plan?" "Eon:" "I don't need a plan to defeat you." "And incidentally, I didn't come alone." "Adult Ben:" "Sure, it's all fun and games until someone loses an eye." "Whoa!" "Eon:" "Any last words," "Tennyson?" "I'm collecting them." "Adult Ben:" "I've got two words for you..." "Ultimate Humungousaur!" "Arcticguana!" "But wait, there's more!" "Heatblast!" "Eon:" "Impressive." "In all my years hunting alternate versions of you, I've never met one with your abilities." "Still, I shouldn't be surprised, considering." "Adult Ben:" "Considering what?" "Why are you doing this, eon?" "When we fought before, we... eon:" "That wasn't me," "Tennyson." "And soon, it won't have been you." "Adult Ben:" "I'm not just gonna stand here and let you nail me with that time-ray." "Clockwork!" "That's right..." "I've got time-traveling powers, too." "Eon:" "No!" "Aaaah!" "Hello, Ben!" "Adult Ben:" "Good to see you," "Paradox." "Love how you don't show up till it's all over." "It's far from over, old friend." "It's barely begun." "Kevin:" "I liked it better when" "I used to drive." "Gwen:" "We do seem to spend less time together since everybody got their licenses." "Ben:" "Well, consider this a reunion." "Kevin:" "Quality time, tracking down the source of the mystery transmission your ultimatrix found." "Ben:" "It's either an uncataloged alien or yet another feature I can't figure out." "Or it's broken again." "[ Beeping ]" "[ Beeping quickens ]" "Gwen:" "Which way?" "Ben:" "We're right on top of it." "Kevin:" "Creepy museum basement." "Figures." "Ben:" "Whatever it is, it's got to be in here." "Gwen:" "There's probably a crowbar around somewhere." "Kevin:" "We already broke into the museum." "What's the big deal?" "Ben:" "Let's see what we've got." "That's weird." "Are those magic symbols?" "Gwen:" "Notin anylanguageI know." "Ben:" "Ow!" "Kevin:" "Howyoudoingback  there?" "Ben:" "I 'vebeenbetter." "Spidermonkey:" "Spidermonkey!" "Kevin:" "Wow." "You learn that in karate school?" "Gwen:" "Sawit in an oldmovie." "Spidermonkey:" "Missedme ." "But I left you a present anyway." "Well, that's the last of 'em." "Whoever they are." "Oh, come on!" "Kevin:" "What'sthebig deal?" "We beat 'em." "Ben:" "Theyescaped,and we don't know what they wanted or even why the ultimatrix led us to them." "Kevin:" "Butotherthanthat ..." "Ben:" "Yeah." "We won." "Youdidn'twin,Benjamin." "AdultBen:" "Maybeyou missed it... bad guy, completely vaporized." "Eonhasnotbeendestroyed." "You merely knocked him down your own timeline." "AdultBen:" "Wait." "He said he's been traveling cross-time." "Do you think he tricked me?" "Intosendinghimintoyour  own past, in order to face you when you were younger and less powerful?" "Yes." "AdultBen:" "I'vegot todo something." "Youalreadyare." "Ben:" "Don't!" "That's how they got out before." "Gwen:" "I don'tthinkso." "I'm getting a weird vibe off of it, almost like I'm sensing my own manna." "I'm gonna try a spell of revelation." "Ostendo specialist." "Ben:" "That'sus whenwewere  kids." "Kevin:" "Youdidaspellto show the past?" "Gwen:" "No." "It's just supposed to reveal secrets." "Ben:" "Who'sthat?" "I don't remember that happening." "Gwen:" "Meeither." "Kevin:" "Youokay?" "Gwen:" "Spell'sbroken." "I don't know why." "Kevin:" "Maybesomebodyerased your memories, or... or, uh..." "Ben:" "Ormaybeitwastime travel and something happened to change our history?" "Adult Ben:" "Good guess." ""Good guess"?" "It's completely wrong." "Adult Ben:" "Well, wrong but clever." "Gwen:" "Professor Paradox?" "Hello, children!" "Kevin:" "Who's your friend?" "Ben:" "Are you..." "Adult Ben:" "That's right, Ben." "I'm you, only even more awesome!" "Adult Ben:" "Ben 10,000 at your service." "Kevin:" "I heard about you." "You're the jerk from the future." "Adult Ben:" "I'm a different" "Ben 10,000." "But I do remember going to that future back when we were 10." "What a buzzkill that guy was." "Ben:" "You'remy realfuture." "Yes, if nothing occurs to change it." "That's why I've..." "Bent the rules of time and brought you together." "Ben:" "We're in trouble." "Adult Ben:" "We've been in tougher spots." "One time, when I was president of earth..." "Ben:" "Wait." "I'm gonna be president of earth?" "Adult Ben:" "Just long enough to defeat the third Vilgaxian invasion." "It turned out that Gwen was better at the day-to-day stuff." "You're a shoo-in for a second term, red." "Gwen:" "Really?" "Spoiler alert, Benjamin." "Let the children discover their own futures..." "If indeed they survive the present threat." "We should take this along." "It's the source of our difficulties." "Okay." "All strapped in." "Kevin:" "You sure about this?" "We're headed to the middle of nowhere." "One only hopes it's far enough." "Kevin:" "Nothing ever makes sense when you're around." "That's a fair criticism." "Kevin:" "Which still doesn't explain how Ben met himself in the future, but it wasn't this guy." "You traveled into cross-time." "Gwen:" "Like a parallel world?" "Exactly." "Ben:" "That's why the me in the future didn't remember it happening to him before." "Both:" "But you remember all of this." "Adult Ben:" "Yeah, I do." "Kevin:" "Okay, don't do that again." "As Gwen guessed, cross-time is made up of parallel versions of the history we know." "There are hundreds of them... a world where Gwen found the" "Omnitrix, a world where albedo turned to alien x and was trapped motionless for nearly a year, a world where you didn't have to destroy the Omnitrix to defeat Vilgax." "Adult Ben:" "Et cetera." "Ad infinitum." "These worlds are all every bit as real as our own, but they cannot... must not... be allowed to leak into ours." "Adult Ben:" "Which brings us to our problem." "Ben:" "The hand of armageddon." "Very good, Ben." "It's a cross-time gateway, existing in many worlds." "Adult Ben:" "You saw into one of them with your spell." "Ben:" "Wait a minute." "If you remember that, if you remember this whole adventure, what's the problem?" "If you're me 20 years from now, we can't lose." "AdultBen:" "BecauseI'm you  20 years from now, if we lose, the future ceases to be." "If you could speed up," "Kevin..." "Kevin:" "Wow, nobody ever asks me to go faster." "It's just that a cross-chronal warp is opening up nearby." "[ Crash ]" "Gwen:" "In the cargo bay?" "I'm afraid so." "I'll see you good people on the ground..." "Probably." "Gwen:" "Not a good sign." "Ben:" "I figured we were toast as soon as Paradox left." "Gwen:" "What do they want?" "Adult Ben:" "To crash us." "Ben:" "Yeah." "No." "Goop:" "Goop!" "The one time I wanted rath!" "Kevin:" "What are you guys doing back there?" "You better not be messin' up my ride!" "[ Rapid beeping ]" "Adult Ben:" "Keep the ninjas away from Kevin." "I'll be right back." "Gwen:" "Where are you going?" "Adult Ben:" "Thought I'd step outside." "Outside." "Jetray!" "Whoa." "Twice in one day." "Or was it..." "Twice in 20 years?" "Kevin:" "The ninjas disappeared as soon as we beat them." "Adult Ben:" "Yeah." "They do that." "Gwen:" "You just landed a spaceship." "AdultBen:" "Fromthe outside." "Don't forget the cool part." "Ben:" "Howdo youdoallthat without transforming?" "AdultBen:" "Ihaven'tbothered to for years." "Not since I discovered my best transformation." "Gwen:" "UltimateBen?" "Ben:" "Whatpowercomeswith  that?" "AdultBen:" "Prettymuchallof them." "You'll figure it out someday." "Kevin:" "Yeah,great." "So, why did we fly the hand of" "Armadoohickey all the way into the desert?" "Todestroyit ." "The ninjas work for a being named eon, a creature from the cross-time earth Gwen showed you with her spell." "AdultBen:" "Eonwas defeated by the Ben of that world when he destroyed their version of the hand." "ThatBenbelievedeon was  destroyed as well, but he wasn't." "He was instead thrown out of that reality and into cross-time." "AdultBen:" "Sincethen,he's  been moving from one parallel earth to the next, taking down every Ben 10 he can find." "Gwen:" "Why?" "Wedon'tknow." "But we do know that he needs an operational hand of armageddon to enter our world." "Kevin:" "Sowe 'regonnabust it." "We'regoingto destroythe  hand throughout space and time... every version." "Kevin:" "Whydon'tyou justdo it with your time-travel powers?" "Therearerules,Kevin." "I cannot interfere." "Gwen:" "Excuseme ,butaren't you already interfering?" "Touché." "Actually, I've just come to give young Ben a warning, but that can wait." "Ben:" "Untilwhat?" "UntilI seeif yousurvive." "AdultBen:" "Ready?" "Ben:" "Ready." "Waybig:" "Waybig !" "Shieldus..." "Ifyoucan ." "[ Cracking ]" "Kevin:" "Isthatsupposedtobe  happening?" "No." "I 'vebeendeceived." "Stop!" "Stop!" "He's using your power to open a breach!" "AdultBen:[Groans]" "Eon:" "I 'mfree." "Waybig:" "Notfor long!" "Eon:[ Laughsevilly]" "Ben: [ Grunting ]" "Eon irradiated way big with accelerated time." "Adult Ben: [ Grunts ]" "I'm afraid he's gone." "Adult Ben:" "So is any other transformation he hits with that beam." "Be careful, Ben." "Ben:" "He's the one who better be careful." "Swampfire:" "Swampfire!" "Ultimate swampfire:" "Ultimate swampfire!" "Take them down hard!" "Adult Ben:" "Accelerate!" "On:" "Tennyson." "Prepare to die." "Ultimate swampfire:" "Maybe later." "Where..." "Ultimate swampfire:" "Right behind you." "How about you explain yourself?" "Why attack me over and over?" "Eon:" "Our paths are intertwined, in this and every other timeline." "It's over." "Adult Ben:" "Give it your best shot, eon." "Diamond doesn't particularly age." "Eon:" "I came here to destroy your younger self, but plans can change." "Adult Ben:" "Contego!" "You hang around an anodite for 20 years, you pick up a few tricks." "Kevin:" "Weird that they don't talk." "Gwen:" "Probably just to intimidate us." "Kevin:" "Maybe." "Makes me curious, though." "Gwen:" "Then let's take a look." "Statua!" "[ Hollow thud ]" "Kevin:" "Huh." "Gwen:" "It's gonna be creepy." "I bet they don't even have mouths." "Kevin:" "Or something worse." "Gwen:" "Ben..." "Get over here!" "Ben:" "This raises some questions." "Kevin:" "Yeah." "Like, where did you learn" "Ninjitsu?" "Eon:" "You've discovered our secret." "Adult Ben:" "You're not destroying Ben Tennysons." "You're absorbing them." "Eon:" "I feed on their power and make them my slaves." "When I absorb you, I'll finally have the strength to replace this timeline with a new one..." "Where I will be the only" "Ben Tennyson that exists." "[ All gasp ]" "I won't allow that, eon." "Eon:" "You cannot interfere, time-Walker, and you know why." "True." "But should you dare proceed, there is nowhere in all of space and time you can hide from me." "Eon:" "I'll burn that bridge when I come to it." "Now, I have a couple of" "Ben Tennysons to absorb." "Ben:" "Eon didn't come through the hand of armageddon... he came from our watches." "Adult Ben:" "And the whole fight, he's been leading us away from it." "Ben:" "Hold him off." "I got something to break." "Jetray:" "Jetray!" "Eon:" "No!" "Kevin:" "Whoa!" "Adult Ben:" "Whoa!" "Gwen:" "Aah!" "Gwen:" "There he is!" "Ben: [ Groans ]" "Not so loud." "I'm trying to sleep." "Then sleep soundly in the knowledge that eon is no more and that all of the cross-time worlds with which he interfered will shortly return to normal." "Ben:" "You knew this was going to happen." "It happened to you before." "Adult Ben:" "Eon had messed up the timelines so bad." "I wasn't entirely sure I hadn't ended up in a parallel world." "I can confirm that this is the original timeline." "But the cost of victory was high." "Young Ben lost way big and both" "Swampfires today." "If only there were some way to restore them..." "Adult Ben:" "Yeah, okay." "I get it." "I'll put them back on your playlist." "Ben:" "While you're at it, how about giving me master control?" "Adult Ben:" "Nice try, but I'm already in enough trouble with" "Azmuth." "There you go..." "I just unlocked everything you've ever become up until now." "Ben:" "Really?" "Thanks!" "Adult Ben:" "I also threw in a few new ones..." "Because it'll annoy Azmuth when he finds out." "Time to go." "But first, a warning to my young friends." "Beware old George." "Beware the creature from beyond." "So long!" "Gwen:" "What did he mean by that?" "Kevin:" "Who knows?" "I never understand what he's saying." "I just tune him out." "Ben:" "Whatever the problem is," "I've got ultimatrix to spare." "It is so hero time!"
