Millenia ago, this slug travelled from planet to planet feeding on the energy of its inhabitants, but then it arrived at the world of Monster Legends and it crashed on the coldest region. Consequently, Slugazoid froze, and that's how he remained until the rain of Stardust hit Monster Legends, waking him up and granting him renewed powers!
Slugazoid is a mediocre Water curser with surprisingly good stats. He mainly plays around with Stamina, using relics, Stamina Removal, Stamina Leak and Max Stamina Decrease. He also has good relics for his role, but his moveset completely screws him over, as his incomplete movepool can hardly make him viable as a denier without relying on relics, where he's easily countered by stamina recovering relics. Overall he should definitely not be your first choice for a Denier.
Since he has a big life stat and has no NER, he is susceptible to tortures. Monsters like Ignis can be a good pair with him. Ignis also has PER, helping Slugazoid deny.
Monsters that can apply accuracy buffs can be good allies as they allow Slugazoid to land Slug Charge more effectively
Counters
Since Slugazoid lacks NER, he is susceptible to tortures, so monsters like Hardy and Seaquake can easily take care of this slug.
Since he lacks PER, monsters like Vanoss2099 can apply Evasion to itself without fear.
Ondana, his counterpart, can restore her team's stamina and apply Stamina Regeneration. She also can apply Team Super Attuned, enjoying the fact that most of Slugazoid's skills are Water-based.
A strong Thunder attacker like Iguanazaur can squish this icy slug.
He is easily denied by anything except Freeze and Total Blind.
