Mighty Mechas
This article is about the devices in Beach Surgery. For the wearers, see Mr and Mrs McRae.
The Mighty Mechas are pendant-mounted motorized exoskeletons worn by Mr and Mrs McRae in Chapter 1 of Beach Surgery. When Katita and the unconscious Leif surprise the elderly couple in their apartment overlooking Bolton Street car park, Mr and Mrs McRae deploy the devices—lightweight frames hanging from neck-pendants that unfold into reinforced arms and shoulders, amplifying the wearers' strength.
What follows is described as a "cartoon battle": the elderly couple, mechanically enhanced, pursue Leif (armed with his hand cannon) and Katita through the apartment in a sequence reading simultaneously as slapstick and threat. The mechas are crude, wheezing, painted in cheerful primary colors—domestic technology repurposed for defense. Leif and Katita escape down a 12-storey stairwell; the pursuit ends in farce.
The Mighty Mechas have become iconic across adaptations. A 2016 Taiwanese animated short stages the battle as kinetic abstraction. The opera piece treats the devices as prosthetic grief—the McRaes fighting against aging and forgetting. A tabletop game adaptation gives the Mighty Mechas mechanical stats and special moves. Their absurdity is generative: some read them as synthesised nature (organic bodies extended by machinery); others as comic relief masking surveillance (the apartment itself watching). Scholars debate whether the exoskeletons foreshadow Leif's wings.
