[POWER RANGERS] Best bond between two female rangers

Who shared the best rapport,bond between two female rangers guys. Normally when there are female rangers, there is lot of ego clashes going on just like in power rangers spd,but in some series there has been a great bond,friendship between two female rangers. But i did not like of all of them,like in mystic force i never thought vida rocca and madison rocca had the best of bond although they were sisters. Same in the case of lightspeed rescue or time force although both female rangers are friends. The best bond i felt was in power rangers samurai between mia and emily. Mia cares about emily more than anything,just like she is her elder sister. Whenever she gets injured, mia is first one to run over to help her or prevent her from any further attacks. Emily also share the same bond with mia just as she stated in the final episode of power rangers samurai before the start of super samurai. What is yours favourite
