6. Old Woman (Worms)
We've all had our run-ins with senior citizens in real life, be it trying to get past one ambling along a narrow path, or suffering with one taking forever to check-out at the supermarket, but Team 17's Worms takes the archetypal old lady villain and raises it to a whole new level. Though as in the above image she might seem harmless enough - an old dear wrapped up in a pink dress and carrying a walking stick - beneath that harmless exterior lies a literally explosive concoction ready to cause mass damage. When you select her as your weapon - probably out of morbid curiosity above all else - she'll slowly saunter over to the selected enemy - while muttering under her breath, of course - before spontaneously combusting in the target's face. The first time you see this, it's a hilarious surprise, and remains my favourite weapon in the entire Worms franchise.
