Hello everyone and welcome to my 260th analysis, this time featuring Kronxian Guard.
Overview: This versatile attacker with great Base Life can be a useful addition to teams that need an attacker who can take care of themselves. Kronxian Guard has a very good Base Strength stat and a good trait evolution as well. In addition, he can be used with a more tanky spread his buffs like Taunt, though it is questionable how good this is. Kronxian Guard's Base Speed unfortunately falls short of the average Base Speed for attackers, leaving him vulnerable to especially Metal attacks. Nevertheless, this monster is a good and versatile attacker that can put in great work.

Rank 0: Stun Immunity: Immunity to a deny type is good to have. It can be better, but it's good.
Rank 1: Stun Immunity + Tough: Hardened variants are amazing to have in this metagame, and Tough is even better than the standard Hardened, bringing Kronxian Guard to a much higher level in viability.
Rank 3: Stun Immunity + Tough + SC: Space-Time: This is a worse Evasion, but it still prevents the damage portion. Considering the fact that Kronxian Guard is slower than most attackers, this is a lifesaver.

Build Explanation:
Bellatrix Masamune is a massive nuke that also prevents enemies from hiding behind defensive effects, by removing buffs before dealing damage. Kronx's Soul has average Base Power, but the Curse it applies is very valuable. Space Rebirth is an extremely powerful utility attack that removes debuffs from Kronxian Guard, gives him Life and Stamina Regeneration, and an extra turn after that to immediately see the effects. The last slot determines his playstyle, and it also depends partly on your preference. Sapphire Blade provides Kronxian Guard with a more immediately powerful AOE with added weird, but appreciated effects: applying Stamina Leak to all enemies and giving Kronxian Guard Damage Boost. Tima Assault is an alternative that gives you Double Damage while protecting you from damage, but you can still be afflicted with debuffs. Lastly, Time Guard is for the tankier playstyle, giving him Taunt, Anticipation and Positive Effects Protection - the latter 2 can allow this move to be used even in more offensive sets if there are extra turn users around, but this depends on you.
2 Strength 1 Speed with Life Mutations is the standard for attacker. Alternatively, 1 Strength can be changed for a Life Rune to allow him to use Time Guard much more effectively. That Rune will have a Strength Mutation.

Teammate Options: The 2 Strength 1 Speed spread is a standard attacker that doesn't need specific allies, but you can capitalize on the fact that he is able to rid himself of debuffs and keep himself alive. Dodge Area monsters can be used alongside the rainbow spread to form the infamous Dodge Area - Taunt invincibility core, where the Dodge Area monster cannot be touched for as long as the Taunt lasts, except with Pierce.
