Ok so after like, forever I finally managed to get down to ten. I hated getting rid of some, but this is it. in order of least to favorite, ignore title.
Reasons for picking who I picked. Rip Jaws barely made it because I like how he is the only water based alien, and his look. Benwolf because he a freaking giant wolf that shoots sonar rings. Wildvine is because of all his nature and stretch abilities. Diamond Head because he looks so cool and has endless creation with his crystals. XLR8 because I love superspeed. Cannonbolt because of his funny character, and his awesome ball of death. Upgrade is cool for his technology ability, which sticks to me. Ditto is funny and I like his design, as well as his cloning abilities. Heatblast because, hence my username, I love all things heat, fire, red, orange. Finally Way big. He is my favorite because HE IS A GIANT 200 FOOT TALL GIANT COSMIC BEAM SHOOTING ALIEN OF PURE COOLNESS.
sorry about that. Anyway that's my list, you guys let me know yours!
