So, is he perfect? The answer is no. He’s great as stand-alone Fighter, but his lack of viable Tags heavily limits his Synergy and consequently, his value in the current Meta.
Oppressive Damage output
SP Rilldo RED is a very powerful Fighter right off the bat. In fact, he gets a 50% Strike Damage Boost for 20 timer counts each time he switches in which, combined with his high Strike Attack stat, really makes him a force to be reckoned with.
His Main Ability Boosts his Damage by 40% and brings his Strike Arts Card Heavy Bleed infliction probability up to 100% for 20 timer counts every time he Attacks with one.
Destroyer of Walls
This Fighter has various Abilities in his toolkit that allow him to be a nightmare to most Defense Fighters.
For starters, he completely nullifies all Cover Abilities that reduce Damage. This is a huge factor against Teams like Regeneration and Future which base their high survivability on these highly Effective Defensive Abilities.
Secondly, he nullifies the resurrection that makes Fighters Restore a portion of their Health when they reach 0. This is not as good as it looks because high-level Players can easily work around it by switching cleverly, but it’s still a serviceable Ability.
Last but not least, his Special Move reduces Enemy Health Restoration by 50% for 20 timer counts, which is yet again a good option to have against Regeneration and Future, who are Teams with great Healing Abilities.
He has high Defensive stats but more importantly, he Heals by 10% each time he switches to standby. While this is not as reliable as more immediate and potent Healing Main Abilities, it’s still great to have considering how unusual it is for highly Offensive Fighters to have effective survival Abilities as well.
Where's Your Tags, King Nothing?
There were rumblings up to his release that he might be tagged as an Android or RegenerationFighter. He wasn’t, and because of that, he has extreme difficulty finding a home in any Team outside of a Red Color Counter Team.
Red Color Counter
Thanks to his Z-Ability and all-around toolkit, he makes for an excellent Fighter in this Team both as a core or bench.
He doesn't put Critical to much use, but this is the last option that can give Strike Attack.
Machine Planet Commander
Draw a Strike Arts Card next. Restores own Ki by 40. +40% to damage inflicted for 20 timer counts. +70% chance to inflict Heavy Bleed for 20 timer counts upon landing a Strike Arts hit. Requirements: 15 timer counts must elapse.
Weapon of Extermination
+50% to Strike damage inflicted for 20 timer counts when this character enters the battlefield. Applies Attribute Upgrade "-100% to enemy's 'Sustained Damage CUT' effects activated when changing cover" to self (cannot be cancelled). Nullifies enemy's "Restores own health when it reaches 0" effects when this character attacks (cannot be cancelled).
Nullifies Abnormal Conditions. Restores own health by 10% when this character is switched to standby.
His “Weapon of Extermination” Unique Ability provides him with a significant Damage Boost every time he enters the battlefield and as well as a nice insurance policy against SP Zamasu RED.
His Main Ability draws a Strike Arts Card and increases his Damage inflicted, which is a ridiculously powerful tempo-play.
SP Rilldo RED has a phenomenal toolkit, allowing him to drill his opponents into the ground with a variety of Strike Damage Buffs. What keeps him from being even higher is a lack of Tags, which limit his Team options significantly.
