You are the bearer of the Omnitrix everything always went wonderfully well you had a favorite alien, that alien was xlr8 who was very fast everything went wonderfully being a hero all that got out of control. One day while you were walking around you noticed that your Omnitrix was not working and suddenly it recalibrated but, an alien managed to save itself and in a green flash appeared xlr8... you were on top of him and he didn't realize it so he just started running with you on top without knowing of your presence

"This place is quite spacious"
