PvE Analysis
Gigantamax Lapras is a wonderful tank, possessing both a decent Defense stat and a gargantuan HP stat. Capable of taking many hits, Lapras excels at anchoring teams and protecting critical damage dealers. Its massive HP stat makes it an amazing healer, as Max Spirit scales off the user's Max HP. Furthermore, having access to a 0.5 second Fast Attack in Water Gun enables Lapras to charge up the Max Meter quickly, allowing Trainers to Dynamax repeatedly in tough boss battles.
As an attacker, Gigantamax Lapras not particularly amazing as its Attack stat is mediocre. It is, however, the only Ice-type Gigantamax and the only Pokemon that simultaneously possesses an Ice-type Max Attack and a 0.5 second Fast Attack. While this makes Lapras a flexible Pokemon, its middling Attack stat prevents it from specializing in that role even with G-Max Resonance's raw power.
Be wary that Lapras's underwhelming defensive typing can betray its strong defensive stats. Having four weaknesses and only two resistances limits the amount of bosses that it may be strong against, and it has to often be wary of their coverage moves. However, there are definitely going to be times where Gigantamax Lapras is optimal due to its strong bulk and resistance set.
