Everything is determined, the beginning as well as the end, by forces over which we have no control. It is determined for the insect, as well as for the star. Human beings, vegetables, or cosmic dust, we all dance to a mysterious tune, intoned in the distance by an invisible piper.

Today's subjects, Legacy Shrapnel and Bombshell!
At last the trio is complete with these releases. It's also the first time they've all been under the same line since G1. Both share the same body, so it's hard to say who the retool. Regardless, they're pretty decent modern updates.

Like Kickback, they have the faux cockpit hatches. In addition, they also feature a fair amount of paint apps compared to other current Hasbro releases. Bombshell even has his stripes.
We can do one better with ToyHax's help.
Shrapnel; BOT MODE
Shrapnel full body shot
Shrapnel gets a lot of detail here. Accent labels on his forearms and calves add some nice techo touches. Lables with black stripes on the feet bring out details lost to a thin coat of yellow paint.  Metallic blue on the torso and purple on his crotch break up the relentless flat black.

a chrome red visor label ups the menace and addition mirrored chrome on hsi mandibles bring it close to that G1 feel.

Even his wepaon gets some love!

STAG BEETLE MODE
pincer mode photos
In beetle mode the chromed pincers take center stage. Red striped labels on the robot shoulders  make the "eyes" pop. Shrapnel regains his red stripes and greeble decals on the thorax. Yellow vents finish the look, again saving us from ebon monotony.

Let's move on.
Bombshell; BOT MODE
Bombshell body shot
Bombshell's makeover is no less dramatic. Red vented labals on the forearms and feet and purple paneling on the calves give some nice visual variey, along with the metallic blue on the wrists.the thighs and crotch get chromed, as well as the upper arms.
Bombshell headshots
Zooming in, ToyHax provides several mirror chrome labels for the head and it's distinctive cover.  In addition to some greeble for the yellow crest, you get labels to cover some of the mold gaps on the cannon/probiscus. The mouthplate is single wrapaound piece, so take extra care applying. Some red chrome for the eyes and matte black for the head round things out.
RHINO BEETLE MODE
Beele mode shots
ToyHax extends the stripes on the thorax and also adds the yellow vents and greeble to the back. The chrome helps the head feel more cohesive.
Bonus stickers
As a bonus, the Bombshell set also includes a sheet of tiny insecticons and cerebroshells  to help dominate your collection, if you're so inclined. 
group shot
All in all these sets are excellent enhancements for Kickback's comrades. With the exception of Bombshell's mouthplate decal, they also easy to apply. Well worth your time and money.
Some notes; Shrapnel comes with some opaque chestplate decals  (seen below) and both have mirror chrome option for their eyes and visor. Remember you're not obligated to use every label. Cuistomize as much or little as you want.
