Okay, so on his way to the gas station, Leon notices that something has crashed into the road ahead on him and quickly pulls over. Curious, he gets out to investigate and finds a white orb nestled inside the small crater that's carved itself into the pavement. Of course as soon as he approaches it, it opens, and the Omnitrix flies out it and attaches itself to his wrist.
Panicked, Leon tries to get it off, even tries using a knife and screwdriver he's got stashed away inside his car to try and pry it off, but it's useless. Seeing as there's nothing more he can do besides chopping off his arm, he leaves the watch alone and continues on his way to the Gas station like he planned. There he meets Claire, and the two make their way into the city as usual, but halfway there the watch starts beeping.
Leon pulls over, worried the thing's gonna exploded, only to find himself engulfed in a bright blue light before his body is suddenly transforming. His whole body changes into a vivid green color before liquefying completely, and now he's no longer human but a weird, goopy, slime monster.
Both him and Claire start screaming immediately.
Claire thinks Leon's dying, while Leon has ZERO idea what's happening to him at all, and they both spend a good five minutes just freaking out before they finally settle down and talk. Being stubborn, Leon still wants to help and asks if he can still continue on with Claire, to which she readily agrees and together they delve back into the heart of Raccoon City.
((As the night goes on, Leon keeps transforming into random aliens for long periods of time. (This is because the watch is trying to sync with his DNA.) It's not until after he transforms into all 10 aliens (the last fight with Birkin) does Leon gain control/usage of the Omnitrix))
((When they first arrive at the station, Leon is still stuck as the alien Goop, but it actually turns out to be a boon when they find out his slime can rapidly heal wounds, something they uses to save Marvin's life.))
((The aliens Leon has access to right now are:
1.AmpFebian 2.XLR8 3.BigChill 4.Humungousaur 5.HeatBlast
6.Upgrade 7.Diamondhead 8. Rath 9.Goop 10.Echo-Echo ))
