A lot of people argued over who is smarter, Grey Matter or Brainstorm. To me, the 10 aliens seen in the intros are sort of an upgraded version, making the first one a predecessor. In my opinion, see this list:

1: Wildmutt to Spidermonkey, involving senses and reflexes 2: Four Arms to Humungousaur, involving strength 3: Grey Matter to Brainstorm or Echo Echo, involving intelligence or being small 4: XLR8 to something 5: Upgrade to Goop, involving elasticity 6: Diamondhead to Chromastone, involving crystals 7: Ripjaws to something 8: Stinkfly to Big Chill, involving flight 9: Cannonbolt to Humungousaur or Jetray, involving strength or transportation 10: Heatblast to Swampfire, involving fire attacks

All in all, each alien is important as the last and just as powerful
