Alright for anyone who didn't see this here's what Alien X is. It looks exactly like the silhouette depicts it except it's blue with tiny stars on it. It's power isn't clear but if I could guess it's that it can either bend reality and/or it can use every alien power in existance. However there is a flaw in it's power. The reason the episode is called X equals Ben plus 2 is because when transformed it's revealed that Alien X is an amalgam of space and time with two entities shaped as giant green faces controling each and when transformed Alien X has the two voices of the entities along with Ben's voice. The one that controls time is called the entity of peace and love and is a harmonious woman. The one controlling space is a stern faced disgruntled aggressive male entity with firm decision. While in Alien X form the two entities and Ben reside in Alien X's brain and debate on decisions on how they should use their power. At first the two allow Ben to use their power because he's new in the fact they need him. The flaw is that the two always argue on how to use their power and rely on Ben as a tie breaker in the decision making process but the thing is, since Alien X has existed forever they're still debating on things like whether or not to save the dinosaurs and are stuck on such things since they never had a third to finish the vote and thus why they need Ben. A major problem is that they want to finish the decisions they never decided on in which there are 80million and thus refuse every proposition Ben puts up for vote, such as lets save the Earth, lets save my friends, or lets destroy the evil aliens. To make matters worse when Ben tries to use the omnitrix while still in Alien X form the two stop him and tell him that Alien X is the strongest alien in existence and they need him so they can finally finish their voting process and state they won't let him leave meaning he can't transform back to help his friends and save the Earth. Eventually Ben gets tired of their arguing with eachother like siblings and insults them so much that the female entity of time begins to cry and it forces the male space entity to succumb to Ben on saving the Earth so he won't continue to make the time entity cry and Ben states he doesn't care anymoire and says he just wants to be himself again and be rid of both of them. The space entity succcumbs and lets him turn into Swampfire and save the day. Afterwards Ben reverts back into himself and when Kevin and Gwen ask why he refuses to ever become Alien X again he states that it's the most powerful Alien he's ever been but that power isn't worth the risk and sulks leaving Gwen and Kevin beffudled and the episode ends. A good episode but Alien X only uses it's power once at the begining of the episode and the rest is Kevin doing some serious damage absorbing new aloids such as alien armor from SevenSeven a new bounty hunter 11 times more powerful than SixSix but is still defeated by Kevin after running in fear from the Alien armored Kevin who proceeds to knock out more aliens with Gwen backing him up wihle they carry a motionless Alien X who was in suspened animation due to the bickering pf the space time aliens and Ben inside Alien X's head. You can guarantee this isn't the last time we'll see Alien X but it'll be limited. Ben'll probably use it in a situation that none of his other aliens can handle in which the space time aliens will frogive him and they'll use their power as one and Ben'll transform back and decide to finally give Alien X a real name and use it as a reserve alien/a secret weapon.
