The Powder Toy

I'm H. Pylori bacteria. You now have gastritis.   The next user is smothered with carbon monoxide.

I guess pretty much all of the toggle-able powered elements could act just like PCLN, where they stay on while being sparked and turn off when not sparked.

Please state an attack. I type on my keyboard.   The next user is hit in the head repeatedly with a keyboard.

I'm still silicon, but in liquid form.   The next user has a ton of lava poured on their bare head.

I am C5.   The next user is crushed and frozen by a c5 bomb. 

I'm stickman falling "nearly the speed of light", which is 3 pixels/frame for some reason. I land safely after my head goes through the ground and back up.   I push the next user ...

The weight is 100000000000 km above my head, so it falls very slowly, allowing me to walk away.   A shark attacks the next user. You are an ordinary human.

As long as it is constructive and not just simply flaming/trolling, the moderator will consider it. Moderators are after all, trying to make the TPT community a better place and giving them feedback ...

However, the bull encounters an extreme amount of heat due to the air resistance at mach 5 and instantly ionizes into plasma.   The next user was the bull.

Would it be fine to add it to the official tpt? I'm sure others would like that setting.   @FeynmanLogomaker: I will check out your mod.
