This was a really dull battle. I mean, both of you kept this endless cycle of opening techniques going. Gecko with his hands still on the ground for the entire battle almost. And Bloo's constant assaults from below, being bafffled away by Gecko with aid of his Sharingan. However Gecko's last move wouldn't quite work. For starters, the D rank pillar isn't large enough to launch you all the way into Mid range. Further more, you say you use your lightning infused sword to cut through the forest trees infront of your path. Then what happens when Bloo explodes the entire forest as a whole. You would receive backfire from the explosions behind and to your sides. Not enough to kill you, but to overall give Bloo the upper hand. Aside from that, I think Bloo was more creative with his bio's main affinity (being wood). While Gecko, did make use of his sharingan, I noticed he didn't use one of it's most famous perks. Which is to detect genjutsu, rather he countered by trying to kill/rid the snakes, without even using his sharingan to acknowledge them as an illusion. To conclude, Bloo's moves were more simple and straight forward, yet made more pressure than Gecko's. Managing to gain the upper hand, offensive-wise. As such, Bloo is the winner. Sorry Gecko.
