The 2005 game Shadow the Hedgehog shows a G.U.N. soldier shoot her in cold blood, while the Sonic X anime shows him kill her when she refuses to comply with his orders.

Shadow the Hedgehog as a character was first introduced in 2001's Sonic Adventure 2 as the 'Ultimate Lifeform', before appearing in his own standalone game in 2005 where he notably wields a gun.
