Cactus is a rainbow I have not had on either Nutaku nor DMM. So this will be interesting.

Initial grading

Stats
Looking at her stats is kind of surprising. Her defense is really awesome. Talk about a wall of a flower knight girl. Unfortunately through, her HP makes that wall not so thick. And her attack is not really bad, but not really great either. That is really disappointing. Why give someone so much defense if they can't do anything with it? I've experience with this on League of Legends as Leona. She can be the tank the drives fear into the other team but she does very little in the form of actual damage. What makes her stand out is her abilities to stun enemies with her abilities. So with disappointing stats, let's look on if Cactus can make it up with her abilities like Leona does.

Abilities
Increasing Attack power for team is noting new or special. Even with the revamping of the Solar Blast, I still do not give it much weight unless you really build a powerful solar team for that sole purpose. But since I am at the stage whether I either annihilate enemies too quick to really consider using it or the enemies are so tough that it doesn't do anything much in the fight. So, unless you are a new player that needs solar blast, abilities like crystal drop are pretty much worthless in my opinion. Critical activation rate is nice ability and the critical damage 40% makes it even better. What really stands out is her 60% chance to act again after attacking. Considering her high trigger rate for her ORAORAORA skill, this can be devastating. So her abilities really do help her out with her lackluster stats.

Against normal enemies, Cactus is going to wreck. Against much stronger that will take more than a couple rounds like Nidhogg battles, she isn't going to last very long at all because of her stats. Unlike a rainbow like Red Ginger who can fit well with just about any team combo, Cactus in my opinion forces you to develop the team around her to make her the most effective; hopefully you have the right girls to do so. A powerful canon yes, but a glass canon that may only survive a couple rounds in higher tier play. Final verdict: B+

Waifu judgment
You don't have a whole lot of green haired beauties in this game, but Cactus is certainly one of them! Physical attributes speaking, I kinda wish her hair was a bit longer and breasts a bit bigger but those are just my preferences. She certainly is a fine looking woman who is also a snazzy dresser. Her outfits in her artwork certainly are colorful and classy. I certainly wouldn't having her as a waifu either. Final waifu verdict: A
