Bebop

This mutant is a Frankenstein's Monster, created from the body of a Guerilla, head of a Boar, and psyche of a Shark.  His body has giant metal plates sewn straight to the skin, and his jaw & throat have been replaced with machines, to allow him to swallow medium creatures whole. He wears a purple mohawk & sunglasses.

Magic Immunity. The construct is immune to any spell or effect that would alter its form, and is immune to necrotic damage.  It has resistance to fire & lightning damage.

Damage Resistance. The construct has resistance to piercing, slashing, and bludgeoning damage from non-magic weapons.

Magic Absorption. Any time the construct is targeted by a spell that deals fire or lightning damage and it succeeds on its saving throw, it regains hit points equal to the amount of damage it would have taken had it failed its saving throw.  If a spell would deal necrotic damage to the construct, the construct instead regains hit points equal to half of the necrotic damage amount.

Magic Weapons. The construct's weapon attacks are magical.

Multiattack. The construct can make two claw attacks, one bite attack, or one Swallow action.

Claw. Melee Weapon Attack: +10 to hit, reach 5 ft., one target. Hit: 20 (3d6 + 8) slashing damage.

Bite. Melee Weapon Attack: +12 to hit, reach 10 ft., one target. Hit: 28 (3d10 + 10) piercing damage.

Swallow. The construct makes one bite attack against a Medium or smaller target it is grappling. If the attack hits, the target must make a Strength saving throw (DC 17) or be swallowed. The swallowed target is blinded and restrained, has total cover against attacks and other effects outside the construct, and takes 15 (4d6) acid damage at the start of each of the construct's turns. The construct can have only one target swallowed at a time. If the construct dies, a swallowed creature is no longer restrained by it and can escape from the corpse using 5 feet of movement, exiting prone.
