A Jax

A Jax, eventually renamed A-Jax, is a vertically scrolling shoot 'em up arcade game released by Konami in December 1987. Similar to Contra and its "Gryzor", there was a European release of the game called Typhoon, which is the name used for Imagine Software's ZX Spectrum, Amstrad CPC, and Commodore 64 ports. The players control a "Tom Tiger" helicopter and later a "Jerry Mouse" fighter jet, and shoot enemies in the air and bomb them on the ground, collecting power-ups and defeating bosses to advance levels.
