Sticking with my current Weird West theme, here are three interdimensional aliens that were produced for Flying Frog's Shadows of Brimstone game - the Harvesters. Using tears in the fabric of space to pass between worlds, these interdimensional travellers cross over in search of raw materials and artefacts to collect. Wearing heavy environmental suits to protect them from the hazards of our reality, the Harvesters are nearly indestructible. Often times they are connected to their own world through long hoses that stretch out behind them and extend back through a shimmering gateway, bringing whatever substances they require to sustain them in our world. Lumbering but ruthless, the Harvesters are relentless in their search for anything of interest or value to bring back to their own dimension.
Harvesters also have several special attacks that can be triggered by Grappling their opponents - when they roll doubles on their Combat to Hit rolls! This double To hit roll determines which special Grapple Attack is triggered and happens even if the double rolled would miss. One ability called Bash means that the Hero hit is Bounced D3 times (just like Dynamite Bounces) in random directions using the Dynamite Bounce Chart. This Bounce will move the Hero model through any other models in the path, but if the space they would end on is already occupied (or would hit a wall), place the Hero in the last unoccupied space moved through.
