Although SD Mega Hera excels as a breaker, its lackluster speed leaves it vulnerable to many faster offensive threats. Examples include Latios, Mega Gardevoir, Mega Diancie, Mega Zam, Jolly Mega Altaria, and several others. Because of this, Mega Hera can often find itself struggling against more offensive playstyles. This is where Jira comes in, being able to check these Pokemon nicely thanks to Choice Scarf and its good set of resistances. Moreover, Jira provides Mega Hera with Healing Wish support. This gives it a second chance to break things apart after getting worn down or crippled by status, which is particularly useful against the defensive playstyles Mega Hera thrives against. Lastly, U-turn is always nice to bring Mega Hera in for free against common Jira switch ins like Ferro and Hippo, who can both be taken advantage of easily by the bug.
How does Jira benefit from Mega Hera as a partner? As said earlier, SD Mega Hera is a great wall breaker capable of breaking down the likes of Skarm, Hippo, Lando-T, and Gliscor. Because all of these Pokemon are things Jira struggles a great deal with, it appreciates them being weakened or eliminated completely. Mega Hera does a nice job doing this, while threatening a number of other defensive Pokemon that give the steel star a hard time, such as Ferro, Rotom-W and Slowbro. Mega Hera's ability to handle Bisharp is also appreciated, as it's one of the biggest offensive threats to Jira.
In sum, Jira helps make up for Mega Hera's low speed and covers its weakness to a host of offensive threats, all while providing Healing Wish support. In return, Mega Hera breaks several of the defensive threats Jira struggles with, which gives it an easier time cleaning late game. The ability these two have to cover the playstyles the other struggles with makes them a relatively good pair.
