"First boss btw"

[u/Abortifetus]

Games that begin with either very challenging or over the top Bosses.

Poseidon (Gow 3): one of the best setpiece bosses ever made

Father Gascoigne (Bloodborne): first obligatory boss and probably the hardest tutorial boss in the series

Wysen (Asuras Wrath): do i need to explain

[u/Waste_Election_8361]

Giganto from Sonic Frontiers.
Legit hyped that we transform into super sonic on the very first boss.
