Hariyama ex

The Hariyama ex card was released in 2005 as part of the EX Deoxys expansion, the sixth installment in the EX series of the Pokémon Trading Card Game. During this era, the Pokémon Company International, then under the management of Nintendo, focused on the introduction of 'ex' Pokémon—cards that featured higher HP and more powerful attacks than their standard counterparts, often balanced by the rule that a player would take two prize cards instead of one upon knocking them out. This set specifically centered on the legendary Pokémon Deoxys and its various forms, reflecting the narrative trajectory of the Generation III games.

The card was illustrated by Hikaru Koike, a veteran artist whose work on the EX series frequently utilized a distinct 3D-rendered style that emphasized the robust, heavy anatomy of Fighting-type Pokémon. Hariyama ex was designed to showcase the Sumo-inspired mechanics of the character, featuring the 'Knock Off' and 'Pivot Throw' attacks that prioritized disruption and high damage output. It was received by the competitive community as a potent mid-game card, valued for its ability to handle high-HP threats within the 2005 competitive metagame.
