Killer toads is a pair of toads acting together so that they can eat certain patterns.

Killer toads can eat a B-heptomino predecessor, as can be seen in the p2 version of 45-degree MWSS-to-G. This happens to the similarly structured middleweight spaceship and heavyweight spaceship, but not lightweight spaceship which leaves a hazardous beehive.

Killer toads can also eat three quarters of a traffic light, which is featured in twirling T-tetsons 2, the 52-cell p146 pi-heptomino hassler and the p2 variant of L122.

Glider synthesis

For a long time, killer toads was known to be synthesizable in 6 gliders from two separate 3-glider toads. On December 24, 2023, Carson Cheng found a 5-glider synthesis for killer toads, followed soon after by another 5-glider synthesis starting from a beehive. On December 27, 2023, a 4-glider synthesis was uploaded to Catagolue.
