Cobalt
In Cobalt, the Spike Bow can be found in Chapter 2 in a small home, owned by a defensive Felishroom.

WASD
In Cobalt WASD, there is a Spike Bow counterpart, the Radioactive Crossbow. This is a Protobot exclusive secondary weapon that costs 25 volts to buy.

The Radioactive Crossbow does 17 damage on impact, 25 damage from behind, 25 damage on the head, and 50 on the eye.

Unlike Cobalt's normal Spike Bow however, this weapon has a 4 round 'magazine.' After the projectile comes into contact with anything, the spike will emit a single radioactive ball, similar to the ones from Radioactive Vials. Radiation damage is consistent at 7 damage per hit.

Trivia
The Radioactive Crossbow is the third way to die by radiation in WASD, the first being the Radioactive Vial's projectiles, and the second being the radiation pit in Boulevard.
